BACKGROUND

The present invention relates to cellular transmission sites.

In contrast to the largely stationary internet of the early 2000s, Americans today are increasingly connected to the world of digital information while “on the go” via smartphones and other mobile devices. Explore the patterns and trends that have shaped the mobile revolution below. The vast majority of Americans—95%—now own a cellphone of some kind.

To support such explosive growth in usage, telecommunication companies (telcos) need many cell towers. Cell tower costs vary widely, depending on what kinds of deals the constructor has with various vendors. Generally, constructing a tower costs around $200,000 or $250,000. About $150,000 of that is for “civil installation” which includes pouring concrete, the mast and its erection, backup generators, fencing, tiny air-conditioned shack, and security systems. The telecommunications guts (baseband processors, transceivers, power supplies, amplifiers, etc) will run about $20,000 to $50,000 for the equipment—and another $25,000 for installation ($75,000 for equipment and installation). There may also be about $5000 worth of costs to connect the tower to the core network, depending on its location and infrastructure. The bulk of the cost is for “civil installation” (standard building materials, construction, and installation costs). A major issue is the permit issuance, which can take 12-36 months to obtain.

Moreover, after construction, the cell towers are exposed to damage from natural disasters since they cannot not be moved to safety. Since the telcos are typically self-insured, the maintenance and support of the cell towers can be substantial.

DETAILED DESCRIPTION

One embodiment of telco shelter 10 of this invention will now be described with respect to FIGS. 1-8. Turning now to FIG. 1, telco shelter 10 includes a main section 12 which has a first end 14, a second end 16, a door 15, a roof 18, a floor panel having a floor surface 22 and four corner posts 20. As shown in FIGS. 13-25 below, telco shelter 10 may further include expandable modules. As further shown in FIGS. 44-52 below, telco shelter 10 may link with other shelters for increased space, support or strength. There are four corner posts 20 which are the main support elements of telco shelter 10. Corner posts 20 may be made of heavy gauge, welded steel. Gusset plates may be provided at the top and bottom ends of posts 20 to provide greater strength and rigidity. Each corner post typically has a connection block 50 attached such as by welding to its top and bottom ends. Each block 50 typically has holes 52 formed in the top and bottom surfaces thereof to allow a standard container connector to be inserted therein. Connectors may be used to clamp telco shelters 10 together vertically. Holes formed on the sides of blocks 50 may be used for interfacing with a crane, forklift or other like mechanism for movement of telco shelter 10 from one place to another.

The telco shelter 10 may have the configuration of a standard ISO container, which is typically twenty feet long, eight feet wide, and eight or nine feet high. As shown in FIG. 1, telco shelter 10 may be stacked on top of other telco shelters 10, or ISO containers with which it is compatible. In this manner, a telco shelter 10 or multiple telco shelters 10 can be shipped by means of cargo aircraft, military aircraft, rail, truck or container ship to a desired location. In one example, two such telco shelters 10 may be accommodated in a C-130 aircraft for deployment. Moreover, the telco shelters 10 may be stacked in a storage facility along with ISO containers. In one embodiment, telco shelters 10 are configured so as to be able to be stacked nine high. Telco shelters 10 a-i preferably are built to satisfy ISO 1496/1 test requirements.

Corner posts are provided at each corner of the telco shelter. These posts are load-bearing, and are reinforced to permit stacking of the telco shelter. The corner posts may be provided with jacks that may pivot outwardly from the post. Typically the jacks are provided with feet, such as sand feet, which assist in stabilizing the telco shelter. The jacks in the posts level the telco shelter. These jacks may be either manually operated, or, if access to power is provided, there is a self-leveling system which automatically levels the telco shelter. Each of the expanded modules of the telco shelter are also provided with stabilizers having feet which permit leveling of those portions of the telco shelter.

The pod is a deployable, expandable, telco shelter which may be expanded from a base condition in which it has the size and shape of a standard ISO container to a condition in which it contains all equipment ready for deployment as a moveable cell tower. The telco shelter can be stacked nine units high for shipping or storage. The telco shelter, when deployed, may be used for increasing capacity for local events, for adding capacity to freeway, hospital, laboratory space, disaster recovery, temporary housing, meeting or office space, or other like purposes.

FIG. 2 shows the components inside the pod of FIG. 1. The pod has air conditioning unit (HVAC) 60 to cool internal temperature. This can be controlled by an HVAC controller 62. A door entry is provided to allow operator access for maintenance, and next to the door is an emergency kit 80. Across from the door entry 82 is an ATS 64 and power bay 66. Equipment rack 68 is provided, and can handle the standard 19-inch racks, commonly for servers or networking devices. A plurality of remote radio head (RRH) 70 and 86, also called a remote radio unit (RRU) is provided for communication in wireless networks. The RRH is a remote radio transceiver that connects to an operator radio control panel via electrical or wireless interface. In wireless system technologies such as GSM, CDMA, UMTS, LTE the radio equipment is remote to the BTS/NodeB/eNodeB. The equipment is used to extend the coverage of a BTS/NodeB/eNodeB in challenging environments such as rural areas or tunnels. They are generally connected to the BTS/NodeB/eNodeB via a fiber optic cable using Common Public Radio Interface protocols. RRHs have become one of the most important subsystems of today's new distributed base stations. The RRH contains the base station's RF circuitry plus analog-to-digital/digital-to-analog converters and up/down converters. RRHs also have operation and management processing capabilities and a standardized optical interface to connect to the rest of the base station. Remote radio heads make MIMO operation easier; they increase a base station's efficiency and facilitate easier physical location for gap coverage problems. RRHs typically use the latest RF component technology including Gallium nitride (GaN) RF power devices and envelope tracking technology within the RRH RF power amplifier (RFPA). Fourth-generation (4G) and beyond infrastructure deployments will include the implementation of Fiber to the Antenna (FTTA) architecture. FTTA architecture has enabled lower power requirements, distributed antenna sites, and a reduced base station footprint than conventional tower sites. The use of FTTA will promote the separation of power and signal components from the base station and their relocation to the top of the tower mast in a Remote Radio Head (RRH). According to the Telcordia industry standard that establishes generic requirements for Fiber to the Antenna (FTTA) protection GR-3177, the RRH shifts the entire high-frequency and power electronic segments from the base station to a location adjacent to the antenna. The RRH will be served by optical fiber and DC power for the optical-to-electronic conversion at the RRH. RRHs optionally has Surge Protective Devices (SPDs) to protect the system from lightning strikes and induced power surges. There is also a change in electrical overstress exposure due to the relocation of the equipment from the base station to the top of the mast. The RRHs can be installed in a low-profile arrangement along a rooftop, or can involve a much higher tower arrangement.

The RRH 70 and 86 have cables that are routed through the RF entry points 72 and connected to an antenna with a mast 78. The antenna mast 78 supports the mounting of antenna. The antenna may be used for reception, transmission or both reception and transmission of an electromagnetic signal. The mast may be limited in height because of obstructions in the environment. Obstructions may include vegetation, vine canopies, tree canopies, bridges, traffic signals, buildings or otherwise. The limitation in height of the antenna may limit the maximum range of effective communications between the vehicle and a communications device located remotely apart from the vehicle. For example, electromagnetic radiation that is in the microwave frequency range may be limited to propagation in line-of-sight paths or may be severely attenuated by ground clutter where antenna height is insufficient for a requisite level of clearance. Accordingly, the mast 78 is used to extend the height for maximizing the available antenna height of an antenna mast mounted on a vehicle to improve the range and reliability of communications. FIG. 4 shows an exemplary interior view of the pod of FIG. 1. FIGS. 5-6 show exemplary front and back sectional view of the pod of FIG. 1, while FIGS. 7-8 show exemplary front and back view of the pod of FIG. 1.

FIG. 3 shows an exemplary mast side and HVAC side view of the pod of FIG. 1. The mast 78 is moved up or down using a pneumatic pump 76 and controlled by a controller. To support raising and lowering of the antenna mast 78, a retractable tensioner can be used for receiving or releasing the transmission line. In one configuration, the retractable tensioner comprises a reel or spool upon which the transmission line is wound to a great extent when the antenna mast is fully lowered and to a lesser extent (or not at all) when the antenna mast is fully raised. The spool may be spring-loaded to retract the transmission line and a releasable ratchet mechanism (e.g., a generally circular gear with teeth, the gear mounted coaxially to the spool, where the teeth engage a movable pawl) may prevent the spool from moving when the tower is elevated above its lowest height. A signal evaluator measures or determines a signal quality level associated with the received electromagnetic signal. The signal evaluator is arranged to compare the measured signal quality level to a threshold minimum signal quality level. The user or a technician may establish the threshold minimum signal quality based on one or more of the following: (1) target reliability (e.g., 99.9% reliability) or target availability of communications (e.g. reception, transmission or both) for the antenna and associated communications equipment, (2) a maximum bit-error rate for digitally modulated signals, (3) a minimum signal-to-noise ratio, and (4) a minimum signal strength. The threshold minimum signal quality may vary with the environment or location of the vehicle and may vary over time, such that time-averaged readings of the measured signal are used for signal quality determinations. In one embodiment, the signal quality comprises the measured signal-to-noise ratio of the received signal and the minimum signal quality level comprises a minimum signal-to-noise ratio defined by a user or technician. In another embodiment, the signal quality comprises signal strength of the received signal, and the minimum signal quality level comprises a minimum signal strength defined by a user or technician.

Further, a power panel 74 receives power into the pod. Power may be provided by line to a connector from a source, such as a peripheral mechanical module to power communications panel. Heating, ventilation and air conditioning may be provided through supply and return ducts which may connect to adapter plates. Communication lines (not shown) may connect with connectors. Clean and waste water lines, respectively, may be connected to adapter plate which is interchangeable with other adapter plates. Power from panel 74 may be supplied to sub panels to supply power to outlet strips (not shown) and lights 84.

A leveling bubble may also be provided for manual leveling of the telco shelter 10. Preferably, however, the telco shelter is self-leveling. A self-leveling control panel 168 allows the telco shelter to level itself through the use of built-in sensors and software. A typical self leveling unit employs an inclinometer and electric motors and gear reducers to operate jacks described below in a known manner to level telco shelter 10.

To enhance placement without requiring a crane, in one embodiment, each post 20 contains a jack. The jack is normally in a stowed or retracted position, and extends in a deployed condition to support the pod when the truck is moved. The jack is then retracted to bring the pod to the ground in a controlled manner and the jack can be removed afterward. Jack typically includes a ram for leveling of telco shelter 10. Typically, each jack is disposed within an interior cavity of post 20 in the retracted position. A cover plate may be disposed on the front of housing. In one embodiment, cover plate may have integral cross bolts that may lock the cover plate and jack in a stowed position. A bracket may be attached to the front of cover plate and may be used to manually pull the jack out of the post 20 and swing it into its deployed condition. There may also be a manual access knob that permits access to a socket for a hand crank that can be used to manually crank down the ram of jack, for leveling of telco shelter 10 in the absence of any power. Alternatively, or in addition, ram may be driven by an electromechanical motor. Electrical power and sensor wires may be attached at connectors at the top end of housing. The bottom end of ram may be filled with a stabilizing foot.

Containers suitable for transportation by truck, ship, or air must generally comply with the standards and regulations for ship freight set forth by ISO and CSC. Furthermore, containers that are transported by helicopter must be able to support the dynamic load imposed by the lifting of the containers, which is typically about three times the static load. Heretofore, such containers generally have a metal framework, i.e., a post-and-beam construction, with composition board (usually steel or aluminum sheathed) or other composite material panels attached to the framework by bolts, rivets, welding, and the like. Such containers, however, are inherently heavy. For example, a standard 20-feet long container constructed to meet ISO size requirements (typically 8 feet wide by 8 feet high) weighs on the order of 4,000 to 5,000 pounds. As a result, the maximum cargo or payload that can be transported in such a container is generally limited to two to three times the tare weight, or empty weight, of the container. Furthermore, the side, roof, and floor panels of the metal-framed container typically do not support any structural loads or provide any structural resistance to externally applied forces. The metal framework of these containers must therefore have sufficient mass and structural strength to support both the cargo load and any externally applied forces. More recently, instead of metal framework, some transportable containers that have been constructed to meet ISO size requirements have been formed of composite material panels. These containers may not be able to handle hurricane level wind. To address this, a base ballast can be used.

FIG. 9 shows an exemplary perspective view of a base ballast for the pod of FIG. 1. The base ballast can be used to anchor the pod to the ground and can sustain hurricane level wind. The ballast can hold material that is used to provide stability to a pod. Material in the ballast can be positioned to affect the pod handling by changing its load distribution or center of gravity, for example.

The base ballast includes a substantially rectangular frame 120 with outriggers 122 sliding in and out of the bottom of the base ballast frame 120. Each outrigger 122 has extended arms 126 that can provide additional securing cables to the pod. At the top of each corner of the frame 120 is a male connector 124 that securely attaches the frame 120 to the pod of FIG. 1. For additional weight, sand, cement, rock, or other objects can be embedded inside the frame 120 to hold the pod to the ground. FIG. 10 shows an exemplary top view of the base ballast of FIG. 9. FIG. 11 shows an exemplary mast side and HVAC side view of the ballast of FIG. 9. FIG. 12 shows an exemplary view of the HVAC side view of FIG. 11 with closed and extended outriggers 122. The outriggers 122 slide in and out of support bars in the frame 120. The frame 120 is further supported by cross bars.

Next, the modular aspects of the pod in accordance with the preferred embodiment are detailed. FIGS. 13-23 show an exemplary views of a split room embodiment of a pod. A pocket door (or a small door) is provided to allow access into the split room. While small, as shown in FIG. 19-20, the split room can contain all amenities of the pod of FIG. 1. For larger requirements, FIGS. 24-25 show exemplary views of a single room embodiment. FIG. 25 shows that the single room embodiment can also have the same equipment as in the pod of FIG. 1.

As cell towers have run into esthetic objections from residents, various embodiments of the pods can be camouflage to better blend into the environment. For example, FIGS. 27-29 show an exemplary green camouflaged pod for placement near nature. FIGS. 30-36 show an exemplary brick camouflaged pod for placement near homes or brick buildings. FIGS. 37-42 show an exemplary sand camouflaged pod for placement near sandy locations.

FIG. 43 shows an exemplary transportation system for the pod. The system includes a trailer with a transport bed adapted to receive a shelter having substantially rectangular base with approximate bottom dimensions of a standard International Organization for Standardization (ISO) freight container. The system also has first and second wheeled transport assembly positioned on the trailer, wherein each transport assembly is adapted to connect to each end of the shelter to move the shelter on or off the trailer. Base locking units at each corner of the bed to be secured to a shelter.

FIGS. 44-45 show an exemplary co-location X-configuration of four pods. In this configuration, the cellular communication system includes a first shelter having pre-configured equipment to communicate with a telecommunication facility, wherein the shelter in combination with one or more additional modular shelters in combination conforms to the approximate dimensions of a standard International Organization for Standardization (ISO) freight container. Additionally, second, third and fourth shelters are connected at one end to an end near the antenna mast, wherein the antenna mast is secured to the first, second, third and fourth shelters, wherein each shelter conforms to the approximate dimensions of the ISO freight container. Each shelter can include:

-   -   a door to enter the shelter;     -   a computer rack to receive computer equipment;     -   a radio unit rack to receive wireless communication equipment;     -   an extendable antenna mast; and     -   air conditioning machine to cool the shelter interior;

In this system, the masts have portions that, as they extend, is usually pinned to secure the current segment and the next segment. However, as pins can fall out, the segments can collapse and cause injury. The hydraulic actuated mast is designed to fit inside the pod. It has a collapsed height of 9′-4″ and can extended to the height of 60′ in one embodiment. The mast consists of structural square steel tubing which telescope one section at a time by 3 stage hydraulic ram. Each section of the mast square tubing has a lock pin/ram push pin cut out, this pin is inserted to the section being erected pushed by the hydraulic ram. When the mast section is at the desired height, the twisklock is engage to lock the section in place for allowing the ram to come down and lift the next section. When the mast section is extended the twisklock handle is rotated to allow the twistlock pin to fully engage and penetrates to two mast section to lock in place so the ram can come down safely to lift the next mast section. The system of FIGS. 56A-56E provide a spring loaded lock system in place of a normal pin, and the lock system has a locked state, where the spring loaded rod extends through the two mast segments by a considerable distance through the two mast segment sides to prevent accidental collapse of the mast segments. Moreover, a lock and open pin is provided to ensure that the rod is at its intended locked or open position.

Similarly, a group of items linked with the conjunction “or” should not be read as requiring mutual exclusivity among that group, but rather should be read as “and/or” unless expressly stated otherwise.

With respect to the use of substantially any plural or singular terms herein, those having skill in the art can translate from the plural to the singular or from the singular to the plural as is appropriate to the context or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

All numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth herein are approximations that may vary depending upon the desired properties sought to be obtained. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of any claims in any application claiming priority to the present application, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.

Furthermore, although the foregoing has been described in some detail by way of illustrations and examples for purposes of clarity and understanding, it is apparent to those skilled in the art that certain changes and modifications may be practiced. Therefore, the description and examples should not be construed as limiting the scope of the invention to the specific embodiments and examples described herein, but rather to also cover all modification and alternatives coming with the true scope and spirit of the invention.

All the features disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative features serving the same, equivalent, or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

Having fully described at least one embodiment of the present invention, other equivalent or alternative methods of providing mobile cellular pods according to the present invention will be apparent to those skilled in the art. The invention has been described above by way of illustration, and the specific embodiments disclosed are not intended to limit the invention to the particular forms disclosed. The invention is thus to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the following claims.

Claim elements and steps herein may have been numbered and/or lettered solely as an aid in readability and understanding. Any such numbering and lettering in itself is not intended to and should not be taken to indicate the ordering of elements and/or steps in the claims.
